Why does the entire document change font when I change one word?

[cerise]

When I am working in a table, or in a normal document, sometimes when I
change a word to bold or italics or change the font size of one word, the
entire document changes too. I can undo the unwanted changes by using Control
Z, but it often leaves the pagination or margins wrong or worse still removes
the bullet points from all my lists. What is making thsi happen and how do I
stop it?
